New Jersey Work Zone Laws

New Jersey doubles the fine for any motor-vehicle violation in a highway construction or repair area, or a signed 'safe corridor' (N.J.S.A. 39:4-203.5). The double applies while the zone is up, not just when crews work, and a missing sign is no defense. Go 20-plus over and you owe a court date. Obey the officer or flagger directing traffic; their orders beat every sign (39:4-80). The statewide handheld ban covers your phone in the zone.

New Jersey Work Zone FAQ

Do work zone fines double in New Jersey?
Doubled. Any motor-vehicle fine is doubled in a highway construction or repair area or a designated safe corridor (N.J.S.A. 39:4-203.5). If a construction zone sits inside a safe corridor, the fine doubles only once. New Jersey doubles the fine for any motor-vehicle violation in a highway construction or repair area, or a signed 'safe corridor'.
What is the work zone speed rule in New Jersey?
Obey the posted limit through the whole construction or repair zone. A missing, moved, or stolen sign is not a defense (N.J.S.A. 39:4-203.5). Exceed the limit by 20 mph or more in the zone and you must appear in court.
Do I have to obey a flagger in New Jersey?
Obey the officer or flagger directing traffic; their orders override every other sign and signal (N.J.S.A. 39:4-80). Disregarding the direction is 2 points, and the fine rises inside a construction zone or safe corridor.
